Write the formal charges on atoms in (i) and carbonate ion (ii) nitrite ion.

Text Solution

Verified by Experts

The formal charges on the atoms in both these ions may be calculated as follows :
(i) Formal charge on atoma in carbonate ion

Formal charge on C atom `=4-0-1//2xx8=0`
Formal charge on double bonded O atom `=6-4-1//2xx4=0`
Formal charge on single bonded O atom `=6-6-1//2xx2=-1.`
(ii) Formal charge on atoms in nitrite ion

Formal charge on N atom =5-2-1/2`xx`6=0
Formal charge on double bonded O atom =6-4-1/2`xx`4=0
Formal charge on single bonded O atom =6-6-1/2`xx`2=-1.
